In any Game Night setting, the No Bullshit Mercy Pie Rule, or NBMP, ensures that established house rules will be followed exactly for each game, and that no half rolls, take backs, do overs, close enoughs, or let'em slides will be accepted.

Furthermore, NBMP absolves the winning/leading individual or team from the obligation to "take it easy on" or otherwise diminish their competitive capacity in favor of the losing/last place individual or team without later repercussions to the friendship.

NBMP can be invoked by any player (with group consensus), but only AFTER at least 75% of game participants have begun consuming alcohol.

Jane: "Well, technically the answer is John QUINCY Adams, but since Mike's in last place, we'll let that slide."
